The probe was slated to circle the Earth twice before beginning a five-day trek to the moon, the Japan Aerospace Exploration Agency (JAXA) has said.Formally known as SELENE, short for SELenological and ENgineering Explorer, Kaguya carries 14 science instruments and two small microsatellites to make detailed maps of the moon's surface, probe its interior and study the lunar gravitational field.</BLOCKQUOTE> <center><a href="http://collectspace.com/review/jaxa_kaguya.jpg" target="AirLock"><img src="http://collectspace.com/review/jaxa_kaguya.jpg" width="400" border="0"></a></center></TD></TR><TR bgcolor="#333333"><TD valign=top>spaced out</TD><TD>I was having a look at the website for the Kaguya spacecraft and was very pleased to see that it is carrying an HDTV camera.

For a higher resolution version of the same, see the video link on JAXA's website.

That is one amazing image, absolutely out of this world!

This is inspirational stuff - just like being there. How high is the spacecraft orbiting?

robsouth

This is how it should look.

According to JAXA, Kaguya is 100 km (62 miles) above the Moon.

In space I guess you can fly in attitude you want so there's no particular reason why the camera/viewer should be feet down when passing over the North pole and head down when passing 'under' the South pole.

I assume 'down' there in Sydney you wouldn't stand on your heads to a polar-orbiting satellite pass over the 'right way up'.

MarylandSpace

The images are just awesome.

cddfspace

Awesome! Do they have plans on taking images of the landing sites? At 62 miles away, how close will the views look?

spaced out

I'd be surprised if the cameras have a powerful-enough combination of lenses and resolution to see anything significant at the landing sites but I could be wrong.

In any case I'm sure they will release high-def stills of those area once the probe has passed over them. Still be interesting to see Hadley Rille and the like.

Very true but it's nice to see Australia looking as it should. Sydney is on the East coast afterall!

I have a question (or perhaps an observation) as to HD resolution vs. the old Apollo Hasselblad images. According to the JAXA web site, the Kaguya imager is 1920x1080, which would make sense since that's the resolution of full HDTV. So, that's around 2 megapixels. By contrast, the resolution of a Hasselblad image exceeds 30 mp.

So, even though the Kaguya images appear spectacular, it would seem that their resolution is still far, far less than the 40-year-old pictures from Apollo (although color accuracy is probably higher). Any thoughts?

spaced out

The high-definition digital images are of course way lower in resolution than Hasselblad stills from the Apollo missions but the comparison should really be with the movie cameras used in orbit.

Philip

Even more amazing is the fact that these images are coming from a Japanese spacecraft. If in Europe or US, the spaceflight program won't get the attention/funds it needs in the future, the Moon might become an Asian affaire...

Philip

Both Apollo 15 + 16 landing sites are listed (Word document) as lunar sites to be used in calibrating the Japanese spacecraft instruments!

robsouth

Just watched the video for the first time, like someone has already mentioned it's just like being there. That view is breath taking.

Scott

A new movie which shows some of the far side has been released.

Around the 30 second mark, Tsiolkovsky Crater appears on the horizon.
